    “A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious at the time the invention was made to a person having ordinary skill in the relevant art. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) secondary considerations (i.e., objective indicia) of nonobviousness when presented.6 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). To show unpatentability based on a combination of teachings, “[a]n obviousness determination [also] requires finding both that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” CRFD” slip op. at 7

    “We find that Petitioner has made a threshold showing that the ’558 Provisional does not provide written description support for claim 1’s pharmaceutical solution consisting of each of the recited elements, including n-dodecyl beta-D-maltoside. It is true that “n-Dodecyl β-D-maltoside” can be found listed in the SIGMA Catalog. Ex. 1026, 316. But Dr. Donovan’s testimony helps put that listing in context. It is merely one among well over 100 ionic and non-ionic detergents listed in the cited six pages of the SIGMA Catalog. See 1026, 316–321; Ex. 1062 ¶ 50. When further considered in the context of paragraphs 150–152 of the ’558 Provisional, which generically suggest that “enhancer” compounds can be used in “some embodiments”—then introducing at least 15 classes of potential enhancers16 including “preferred” lysophospholipids and acyl carnitines—the listing of n-dodecyl beta-D-maltoside among at least 150 biological detergents in the SIGMA Catalog is even more remote. Moreover, although satisfaction of the written description requirement is not limited to what is exemplified in a priority application, none of the ’558 Provisional’s examples use any “enhancer,” much less any detergent, any alkyl glycoside, or n-dodecyl beta-D maltoside in particular.

With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

    “parties, we do not find the merits to be particularly strong on the current record. For example, limitation [1-4] recites, in part, “a locking nut having . . . an external thread on an outside surface of the locking nut.” Ex. 1001, 9:46–47. In alleging obviousness based in part on Orphanos, Petitioner equates the claimed “locking nut” to Orphanos’s collet 230 in a first embodiment of Orphanos, or Orphanos’s collet portion 1052 in a second embodiment of Orphanos. Pet. 37–38. Petitioner acknowledges that the collet and collet portion do not have external threads, but rather are designed to have a snap-fit engagement with the inner sidewall of the baseplate’s central throughbore. Id. at 38. Petitioner argues that modifying the collet and collet portion to have external threads would have been obvious to the skilled artisan in view of Orphanos’s teachings and the knowledge of a person having ordinary skill in the art. Pet. 38–42 (arguing, inter alia, that it would have been “a substitution of a known part for a known problem” and “obvious as a matter of design choice”). Petitioner does not allege that replacing the snap-fit coupling with external threads would either: (1) result in any advantages; or (2) preserve any of Orphanos’s stated benefits of its snap-fit arrangement. See Pet. 34–37. That Petitioner describes no advantages to making its proposed modification potentially undermines Petitioner’s case that the skilled artisan would have done so. Cf. Winner Int’l Royalty Corp. v. Wang, 202 F.3d 1340, 1349 n.8 (Fed. Cir. 2000) (“The fact that the motivating benefit comes at the expense of another benefit . . . should not nullify its use as a basis to modify the disclosure of one reference with the teachings of another. Instead, the benefits, both lost and gained, should be weighed against one another.”).” slip op. at 16

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITANot reached

    “Petitioner’s arguments regarding the central post and locking nut include an implicit claim construction argument that these components need not be separate structures. Pet. 74, 76–81. Patent Owner, on the other hand, would have us interpret the claim to require that they be separate structures. Patent Owner raises credible evidence to support its theory. Specifically, Patent Owner directs us to the language of claim 1, which separately recites “a central screw” and “a locking nut.” Prelim. Resp. 51; see Ex. 1001, 9:44–53. Patent Owner further contends, in view of the claim language, that the claimed central post and locking nut are separate and distinct components. According to Patent Owner, however, Lefebvre’s main head and anchor rod portions are parts of a single monolithic anchoring screw. Prelim. Resp. 53–58. Where a claim lists elements separately, there is a rebuttable presumption that these elements have separate and distinct physical structures. See Google LLC v. EcoFactor, Inc., 92 F.4th 1049, 1058 (Fed. Cir. 2024) (citing Powell v. Home Depot U.S.A., Inc., 663 F.3d 1221, 1231–1232 (Fed. Cir. 2011)). The presumption may be rebutted by the intrinsic record. Id. At this stage, however, Petitioner does not address that claim 1 appears to separately recite a central post and a locking nut, and does not direct us to any portion of the intrinsic record that might rebut the presumption that these elements are, therefore, separate and distinct structures. See Pet. 73–77. Petitioner also argues that the claim terms “baseplate central channel” and “central channel . . . configured to interface with the baseplate” are indefinite. Pet. 95–102. Patent Owner argues that the plain and ordinary meaning of the terms is clear and that Petitioner “had no problem” arguing how the asserted art purportedly rendered the claims obvious. Prelim. Resp. 69–77.” slip op. at 17

Patent Owner argues that the plain and ordinary meaning of the terms is clear and that Petitioner “had no problem” arguing how the asserted art purportedly rendered the claims obvious. Prelim.

In sum, even if Petitioner’s contentions show it is more likely than not that at least one of the claims challenged in the Petition is unpatentable, we find Patent Owner’s arguments identify credible weaknesses in Petitioner’s contentions. Accordingly, we find that that the sixth Fintiv factor is neutral and does not weigh against discretionary denial.” slip op. at 18

    “On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding. Further submissions by the parties may include argument and evidence that would assist in the resolution of this issue at the close of trial.” slip op. at 8

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached

    “Petitioner contends “no formal claim construction is necessary in this proceeding.” Pet. 10; Reply 1, 4. Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S. Ct. at 1359–60) is not based on construing the term “mesh layer” or “coefficient of friction,” we determine we need not construe either claim term at this stage of the proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

    “We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci.

Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13
